I have laptop with trackpad mouse.This happens randomly. Yes. Randomly.Sometimes DSL regonizes when I double click with trackpad (With pad, not with buttons. Buttons still work always.)

Sometimes double clicking pad won't work. Only way (I have discovered) is to reboot. And sometimes it works just fine. I have configured mouse several times again and again when it does not work. Only rebooting will help. Somtimes I have to reboot several times in a row to make it work. This doesn't bother me much, but other DSL users may find this annoying.

For example, if you have a Synaptics or Alps touch pad you could use the synaptics driver with XFree86 and turn off clicking and double-clicking on the touch pad by modifying the XF86Config-4 file settings
